Effect of Annealing on Structural, Textural, Thermal, Magnetic, and Luminescence Properties of Calcium Fluoride Nanoparticles

Mesoporous nanocrystalline CaF 2 powder was produced by pulsed electron beam evaporation (PEBE) in vacuum. The specific surface area (SSA) of CaF 2 nanopowder (NP) reached 88.7 m 2 /g. The effect of in-air thermal annealing in the temperature range of 200–900°C on the particle size, morphology, text...
